Surah 13

Surah 13:17

"He sends down water from the sky, and the wādīs flow, (each) in its measure, and the torrent carries a rising (layer of) froth (on top), like the froth that arises from what they heat in the fire, seeking some ornament or utensil. In this way God strikes (a parable of) the true and the false. As for the froth, it becomes worthless, but as for what benefits the people, it remains on the earth. In this way God strikes parables."
